Unformatted text preview: cementation, porosity, pore fluid Igneous rocks – composition (esp. silica content), crystal size, fracturing (i.e. porosity) Metamorphic rocks – composition (esp. silica content), metamorphic grade, fracturing (i.e. porosity) Porosity and pore fluid content are probably the most important factors affecting density in the shallow sub-surface...
